Answer: Yeah, C is correct.
Step-by-step explanation:
120 miles! 6 (inches) x 20 (miles per inch) = 120, and it is of course miles, not inches, so:
-120 miles
9 inches is the longest length of boards he can cut
X- the miles Hans is driving
51,96+0,12*x=45,96+0,14*x
51,96-45,96=0,14x-0,12x
6=0,02x
x=6:0,02
x=300 miles
